Any chance of getting a good clear straight on close up of the decal with no flash from the seller Al?
Everything else looks fine, but making out the details of the decal with those angled shots
is awkward to say the least.

A shame about the broken chinstrap, but these can be replaced fairly easily. I can see no obvious problems with this one, otherwise. Personally, I wouldn't worry about the decal. It's not an SS and just a normal Heer, so no big fret there. If the price is reasonable, I can see no reason to avoid this one.

You always want to check decals closely. Always.
I know someone who can take splice a decal, chemically age it and nobody will know unless there's a pre-restoration photo of it. His specialty. Heer helmets just like this one.
